I see alot of talk about getting Ca to 85% base saturation to maximise uptake. How high do I want the Ca to get in plant tissue analysis though?


I see some people talk about 8-10%? Is this the number I am shooting for in all crops? herb, peppers, tomatoes etc. If not than what is?

this study suggests up to 4% calcium in herb. an interesting read

This reference is to blueberries but plant tissue analysis in cannabis can be misleading.

Growers often apply foliar calcium even when soil and tissue analyses indicate levels are sufficient. This is because sufficiency in soil and leaf tissues does not necessarily indicate that fruit calcium levels are sufficient for a given blueberry cultivar and/or production setting.

The sufficiency range for calcium in cannabis is 1.47 - 4.42%. There's a good read on cannabis sufficiency ranges here https://manicbotanix.com/cannabis-nu...rop-nutrition/

We normally see 6 to 10% in the leaves when running 85% Ca+

Has a lot to do with the rest of the feeds, dry downs and getting enough micros in and at the right proportion.

Glad to hear you are "hearing alot about 85% Ca"!!

Was it Spectrum who will run cannabis analysis if labeled basil or something?

I'm having a hell of a time cloning and I am speculating it goes back to discussions about having enough calcium to ride out any efforts to senesce before rooting or seeing a surge in Ca before cambium begins to create new xylem/phloem/root mass.

Logan. Dry til crispy yet green. Grind the sample in your hands,take out the majority of the vein and send them half a baggy. Call in comfrey. haha

Spectrum is where we do the soil and media analysis.

[bsgospel]

And Spectrum still honors the K3 package for soil? Or was that Logan as well?

Thank you!

[slownickel]

K 3 is for a dried, sifted medium at Spectrum.

Interesting. Have you got any cannabis tissue analysis results to demonstrate this inline to other nutrients also?
